Application filed July 20, 1889. Serial No. 318,188. (No model.)Patented in Belgium June 7, 1889, No. 86,561; in France June 7,1889,N0.198,799; in Germany June 7,1889, No. 19,718 in England June 7,1889,No. 9,432; in Switzerland June 8, 1889, No. 1,099; in Italy June 30,1889, XXIII, 25,781, and L, 448, and in Austria-Hungary October 24,1889, No. 25,468

and No. 76,839.

To all whom it may concern.-

Be it known that LGEORGALBERT GREEVEN, civil engineer, a subject of theKing of Prussia, residing at Crefeld, Prussia, German Empire, haveinvented certain new and useful Iniprovements in Apparatus forImpregnating, \Vashin g,andDyein g Yarn in Hanks or Skeins, (for which Ihave obtained Letters Patent in the following countries: in Belgium June7, 1889, No. 86,561; in France June 7,1889,No. 198,790; in Germany June7, 1889, No. 49,718; in Great Britain June 7,1889, No. 9,432; in ItalyJune 80, 1889, XXIII, 25,731, and L, 4 18; in Austria-Hungary October24:, 1889, No. 25,468 and No. 76,839, and in Switzerland June 8, 1889,No. 1,099,) and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use thesame,reference beinghad to the accompanying drawings, and to letters ofreference marked thereon, which form a part of this specification.

' Figure 1 is a vertical sectional elevation of a washing or dyeingapparatus constructed according to my invention, and Fig. 2 is a sectiontaken on line 0c of Fig. 1.

In the washing or dyeing of yarn in the hank as heretofore effected theyarn was suspended in the dye vat or beck so as to be immersed in thebath for about one half of its length, the parts being spread uponsupporting-rods placed across the vat or beck, and were shifted toimmerse the other half until the operation of dyeing was completed, thedyed portion being alternately immersed into the dye-liquor and exposedto the action of the atmosphere. This operation requires time, andespecially care,in order to obtain a yarn uniformly dyed, and to preventthe yarn from tangling during the shifting of it the time occupied andthe care required being much greater than when the yarn is passedthrough the dye-beck in an endless sheet or belt, in which latter caseit is also difficult to obtain a uniform depth of color.

The object of my invention is to provide a simple apparatus for dyeingyarn in' the hank by the former method and whereby the labor of shiftingthe, yarn is done away with, (the liquid itself being shifted) andwhereby at each immersion the whole of the hank will be immersed in thedye-liquor.

To these ends the invention consists in the combination, with thedye-beck, of means for supporting the hanks of yarn,a locking device tolock the supports against motion, and means for exhausting the dye-beckof its dyeliquor and returning the same thereto, substantially ashereinafter described, and as set forth in the claim.

In the drawings, A indicates the dye-beck, to the sides of which aresecured racks (Z and e, that have notches or recesses cl 6',respectively, for the endsof the supporting-rods b for hanks of yarn a.

f and g are locking-rails,tl1at seat upon the racks cl and 6,respectively, to lock the rods 1) against vertical motion, yet thenotches or recesses in the racks are preferably of such depth as toadmit of a slight rising-and-falling motion of the rods 1). The saidrails are looked to the racks by latches h, pivoted to the side walls ofthe dye-beck. The hanks of yarn are strung loosely on the rods, so'thaton the inflow of the dye-liquor they will rise slightly with it, so thatthe threads thereof will become separated to afford access thereto ofthe dye-liquor.

Any suitable means may be employed for alternately exhausting thedye-liquor from returning it to the dye-beck at a point proximate to thebottom thereof.

In the drawings I have shown an elevated reservoir B of such a capacityas to hold approximately the entire charge of dye-liquor to be used inthe beck A, said reservoir being connected by a pipe 0 with the saiddye-beck near its bottom. The reservoirB is connected by a valved pipeis with any suitable air-exhaust apparatus and is provided with anair-cock Z.

The operation of this apparatus is as follows: The dye-beck A is firstcharged with the necessary amount of dyeliquor. A partial as to draw thedye-liquor into said reservoir. The rods b supplied with the hanksofyarn to be dyed are now locked in the dye-beck, as described, and thestop-cock Z is opened to admit air to reservoir B and allow thedyevacuum is then produced in the reservoir 13, so 9 liquor to flow backinto the dye-beck, so that the hanks of yarn will be entirely immersedin the dye-liquor. After the hanks a have been exposed to the action ofthe dye-liquor the stop-cock lis closed and that in pipe 7; opened, anda partial vacuum produced in reservoir B to draw the dye-liquor into thelatter until the hanks are completely exposed to the action of theatmosphere, and this operation is repeated until the hanks are properlydyed. As the dye-liquor rises in the dye-beck, the hanks float and aremoved about more or less, thereby separating the yarn threads, and thusadmitting the dye-liquor thereto; but the hanks cannot rise with thedye-liquor by reason of theirsupporting-rods b being locked against suchmotion, there being one such rod at each end of the hank, and of coursethe latter cannot fall with the dye-liquor, but remain suspended in theheck after said liquor has been introduced or withdrawn. Of course it beunderstood that the means for introducing the dye-liquor into andexhausting the samej'from the dyerbeck may be greatly ar T s may b ne byea Of a pump or by air or steam pressure, and the reservoir B for thedye-liquor may in this case be located at any convenient pointrelatively to the dye-beck (even below the same) and the beck drained init.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s

The improvements in apparatus for dyeing yarn in the hank, whichconsists in the combination,with an open dye-beck and rods arranged inpairs one above the other for supporting hanks of yarn, said rods havinga slight vertical play in the beck to allow the hanks to float in thedye-liquor, of a closed reservoir, an air-valve for admitting airthereto, and means for exhausting the air from said reservoir,substantially as and for the purposes specified.

In testimony whereof I affix my signature in presence of two witnesses.

GEORG ALBERT GREEVEN.
